Abstract
In cases where decided that the guaranteed resource capacity for virtual machine cannot be acquired all at one time, the computer system of the present invention decides whether or not resource capacity guaranteed for virtual machine can be continuously acquired by the start of the virtual machine operation, and if decided that the resource capacity can be continuously acquired, the computer system allocates the total acquired resource capacity to the virtual machine deployed on the physical machine.
Claims16
A computer system comprising:
- a plurality of physical machines;
- and
- a management computer to manage the plurality of physical machines,
- wherein the plurality of physical machines each include:
- a memory to store the programs to create virtual machines;
- a first controller to create virtual machines by executing programs, to allocate resources to the created virtual machines, and to operate the applicable virtual machines,
- wherein the management computer includes a second controller to manage the allocation of resources to the virtual machine,
- wherein the second controller sets a physical machine capable of continuously acquiring the resource capacity required by the applicable virtual machine by the start of the virtual machine operation, and installs the virtual machine in the applicable physical machine, and
- wherein the first controller of the physical machine where the applicable virtual machine is installed, operates the applicable virtual machine by allocating the required resource capacity to the installed virtual machine.
A control method for a computer system including a physical machine to operate a virtual machine;
- and a management computer to manage the allocation of resources by the physical machine to a virtual machine, the method comprising:
- the management computer deciding whether or not the guaranteed resource capacity for the virtual machine can be continuously acquired by the start of the virtual machine operation, when a decision was made that the guaranteed resource capacity for the virtual machine cannot be acquired all at one time, and
- when deciding that continuous acquisition by the virtual machine start time is possible, the management computer allocating the total acquired resource capacity to the virtual machine, and installing the applicable virtual machine in the physical machine.
A management computer for a plurality of physical machines, to generate virtual machines, allocate resources to the generated virtual machines, and operate the applicable virtual machines, comprising:
- a controller to manage the allocation of resources to the virtual machine,
- wherein the controller,
- decides a physical machine capable of continuously acquiring the resource capacity required by the applicable virtual machine by the start of the virtual machine operation,
- installs the virtual machine in the applicable physical machine, and
- allocates the required resource capacity to the applicable virtual machine installed in the physical machine in order to operate the applicable virtual machine.
A physical server comprising:
- a virtual machine;
- a pool to acquire a resource;
- and
- a controller to allocate the acquired resource from the pool, and operate the work-task system based on the resource allocated to the virtual machine,
- wherein the controller continuously acquires the required resource capacity for the applicable virtual machine, and allocates the required resource capacity from the applicable pool to the virtual machine by the start of the virtual machine operation.
